Ms. kendrick plans to buy a laptop for $1,345 in 12 weeks. she has already saved $145. how much should she save each week so she can buy the laptop?

Set up an equation based on the information given.

12x + 145 = 1345

Solve the equation to see how much she needs to save each week.
First, subtract 145 from both sides.

12x = 1200

Divide 12 off of both sides to find the value of x. 

x = 100
